Our portfolio

Best-in-class tools.
Honestly recommended.

Each partner was selected on merit. Procusec only represents vendors we'd recommend to a CISO who asked us with no commercial relationship in the room.

Eight specialist vendors covering email security, ransomware resilience, network detection & response, secure access (SASE), data security, attack simulation, and exposure management. Together they address the most critical gaps in the modern enterprise security stack.

Abnormal Security

Email Security · BEC Prevention

Legacy secure email gateways were built for a world of mass phishing. Abnormal was built for the age of AI-generated, surgically targeted attacks. Its behavioural AI baseline models every employee and vendor relationship — detecting account takeovers, BEC, and supply chain fraud that bypass every filter-based tool in the market.

Killer use case: Your CFO receives a payment redirection request that perfectly mimics your CFO's writing style. Abnormal catches it. Your SEG doesn't.

Halcyon

Endpoint Security · Ransomware Resilience

Halcyon is the only endpoint security platform built specifically to defeat ransomware — not as a side effect of generic malware detection, but as its primary design objective. It prevents encryption, captures decryption keys when prevention fails, and guarantees business continuity. Purpose-built for the threat that costs enterprises most.

Killer use case: A ransomware strain bypasses your EDR. Halcyon's resilience layer captures the key, halts encryption, and recovers files automatically. Zero downtime. Zero ransom.

Vectra AI

Network Detection & Response · NDR

Once attackers are inside the network, speed of detection determines the outcome. Vectra's AI models attacker behaviour — not signatures — across hybrid cloud, on-premise, and OT/IoT environments, surfacing real threat signals and suppressing alert noise. It gives SOC teams the context to act in minutes, not days.

Killer use case: A compromised service account begins slow lateral movement. No malware. No signature. Vectra identifies the attacker behaviour and creates a prioritised, attributed alert before the blast radius grows.

Netskope

SASE · Security Service Edge · ZTNA

Netskope is a leader in Security Service Edge (SSE) and a founding pillar of the SASE architecture. It provides inline inspection of cloud traffic, zero-trust network access, and best-in-class CASB and DLP capabilities — all delivered from a purpose-built cloud platform. Purpose-built for the reality that the perimeter no longer exists.

Killer use case: Your workforce is fully remote and spread across dozens of SaaS tools. Netskope secures every user, device, and application connection — with granular data controls — without routing traffic through an ageing VPN chokepoint.

CATO Networks

SASE · SD-WAN · Cloud-Native Network Security

CATO Networks built the world's first purpose-built SASE platform — converging SD-WAN, firewall-as-a-service, zero-trust network access, and threat prevention into a single, globally distributed cloud network. No appliances, no management sprawl. One vendor, one policy, one platform for all sites, users, and cloud resources.

Killer use case: Your enterprise has 30 branch offices, 2,000 remote workers, and a patchwork of legacy MPLS and VPN appliances. CATO replaces the entire stack with a single cloud network — reducing cost, complexity, and attack surface in one move.

Harmonic Security

AI Data Security · DLP for GenAI

Your employees are using ChatGPT, Microsoft Copilot, and dozens of other AI tools — with sensitive customer data, source code, and internal documents. Harmonic provides real-time visibility and control over what data flows into which AI tools, without blocking productivity or generating thousands of false-positive alerts.

Killer use case: A developer pastes proprietary source code into an external AI coding assistant. Harmonic detects, classifies, and blocks the submission in real time — and logs the event for compliance reporting under NIS2.

Horizon3.ai

Autonomous Pentesting · Attack Validation

NodeZero is Horizon3's autonomous penetration testing platform. It thinks like an attacker — chaining together misconfigurations, weak credentials, and vulnerabilities to find real attack paths through your environment. Run it continuously, not just once a year. Fix what an attacker would actually exploit.

Killer use case: Your annual pen test found 200 vulnerabilities. NodeZero runs autonomously, chains three misconfigurations into a domain admin compromise, and tells your team exactly which two to fix first.

Daylight Security

Exposure Management · Attack Surface

Vulnerability management programmes produce more risk data than any team can action. Daylight applies attacker-perspective intelligence to prioritise what's exploitable, not just what's technically vulnerable. It contextualises CVEs against your actual environment so teams spend remediation time where it genuinely reduces risk.

Killer use case: Your VM tool flags 4,000 high-severity CVEs. Daylight reduces that to 23 that are exploitable in your specific environment, ranked by likely attacker path. Your team knows exactly where to start.
